 This example shows how Lity and CyberMiles Virtual Machine helps users to avoid potential security issues of number overflow.
 
-Install lity branch of Travis
+Run a CyberMiles Local Node
 -----------------------------
 
-First we need to use lity branch of travis:
-
-.. code:: bash
-
-  # Get lity branch of Travis
-  go get github.com/CyberMiles/travis
-  cd $GOPATH/src/github.com/CyberMiles/travis
-  git checkout lity
-
-  # Install libeni
-  sudo rm -rf $HOME/.travis
-  wget -O $HOME/libeni.tgz https://github.com/CyberMiles/libeni/releases/download/v1.2.0/libeni-1.2.0_ubuntu-16.04.tgz
-  tar zxvf $HOME/libeni.tgz -C $HOME
-  mkdir -p $HOME/.travis/eni
-  cp -r $HOME/libeni-1.2.0/lib $HOME/.travis/eni/lib
-
-  # Build & Install Travis
-  cd $GOPATH/src/github.com/CyberMiles/travis
-  make all
-
-Run Travis locally
-------------------
-
-Then start a  Travis node locally.
-
-.. code:: bash
-
-  # Initial & start
-  travis node init
-  travis node start
-
-Lity compiler
--------------
-
-Build our Lity compiler from source to get :code:`lityc`.
-
-.. code:: bash
-
-  git clone https://github.com/CyberMiles/lity.git
-  cd lity
-  git submodule update --init --recursive
-  mkdir build
-  cd build
-  cmake ..
-  make
-
-Now we have :code:`lityc`:
-
-.. code:: bash
-
-  $ ls -l ./lityc/lityc
